 * $Revision:   1.4  $ $Date:   27 Jul 1992 19:52:06  $
 * $Log:   R:/MIBTOOLS/V1.0/SMIC/SRC/SMEXT.C_V  $
 * 
 *    Rev 1.4   27 Jul 1992 19:52:06   gfoster
 * Changed the variable name fNoCheckIndxSeq
 * to fCheckIndxSeq to accommodate the -7
 * option providing stricter index item checking
 * instead of looser checking.
 * 
 *    Rev 1.3   08 Jul 1992 17:30:34   gfoster
 * Removed unnecessary revision comment lines added by
 * PVCS to make revision history easier to read.
 * 
 *    Rev 1.2   29 Jun 1992 20:01:28   gfoster
 * Changed the path name separator character in UNIX
 * from chSepChar = ';' to chSepChar = ':'.
 * 
 *    Rev 1.1   19 Jun 1992 16:04:24   gfoster
 * Copyright text was reformated.
 * 
 * The misspelling of "not-accessible" was corrected.
 * 
 * Dump of Opaque will print size, if given in MIB.
 * 
 * Dumps work with excluded objects.  The OID list
 * name list, and MOSY lists don't print the excluded
 * objects, dumps do.
 * 
 * Corrects print of OID value is not defined.
 * 
 * The OID list also prints the traps in the MIB.
 * 
 *    Rev 1.0   27 May 1992 16:15:40   gfoster
 * Initial revision.
